MHB What Defines a Nonreflexive Relation in Set Theory? I am reading the book: "Discovering Modern Set Theory. I The Basics" (AMS) by Winfried Just and Martin Weese. I am currently focused on Chapter 2: Partial Order Relations ... I need some help with understanding the meaning of "no...
These meaningful ideas are realized in the precise terminology of set theory (algebra) and mathematical logic. The first of these precise reformulations reflects the extensional aspect of the concept of relation, and the second reflects the intensional (meaningful, contensive). In set-theoretic ...

(In set theory, a relation is untyped and specified as set of pairs. Strictly speaking, the relations we have introduced in Section 2 are typed and consist of source, target and set of pairs.) Let r be the set of pairs contained in R:X↔X, the function c:X→2X implement...
In theory, there is no upper limit on the number of partitions. When creating a table without Partition, the system will automatically generate a Partition with the same name as the table name and a full range of values. The Partition is invisible to the user and cannot be deleted or modi...

In subject area: Mathematics A proper relation algebra P=〈P,∅,U,\,∪,IdB,−1,|〉 is a set P of binary relations over some base set B, containing the binary relations ∅, U (the ‘unit’, an equivalence relation on B), IdB={(x, x): x ∈ B}, and closed under the for...
